FIELD: process engineering.SUBSTANCE: invention relates to machine building and instrument making, particularly, to relaxation of residual stress in parts with ID and OD. Three revolving rolls are bought in contact with part to cause its elastic strain. Strain force is defined from the formula:where ?is part material elastic limit, MPa, K=0.094, d is part ID, mm, W is modulus of bending resistance, mm.EFFECT: higher efficiency of processing, expanded performances.3 dwg |
